Leaving the Vehicle with the Engine
Running
Warning
It can be dangerous to leave the vehicle
with the engine running. It could
overheat and catch fire.
It is dangerous to get out of the vehicle
if the shift lever is not fully in P (Park)
with the parking brake firmly set. The
vehicle can roll.
Warning (Continued)
Do not leave the vehicle when the engine
is running. If you have left the engine
running, the vehicle can move suddenly.
You or others could be injured. To be
sure the vehicle will not move, even
when you are on fairly level ground,
always set the parking brake and move
the shift lever to P (Park). See Shifting
Into Park 0 133. If you are towing a
trailer, see Driving Characteristics and
Towing Tips 0 153.
If you have to leave the vehicle with the
engine running, be sure the vehicle is in
P (Park) and the parking brake is firmly set.
After the shift lever is moved into P (Park),
hold the regular brake pedal down. Then,
see if you can move the shift lever away
from P (Park) without first pulling it toward
you. If you can, it means that the shift lever
was not fully locked into P (Park).
Torque Lock
If you are parking on a hill and you do not
shift the transmission into P (Park) properly,
(Continued)
the weight of the vehicle can put too much
force on the parking pawl in the
Driving and Operating
transmission. It might be difficult to pull the
shift lever out of P (Park). This is called
torque lock. To prevent torque lock, set the
parking brake and then shift into P (Park)
properly before you leave the driver seat. To
find out how, see Shifting Into Park 0 133.
When you are ready to drive, move the
shift lever out of P (Park) before releasing
the parking brake.
If torque lock does occur, you might need to
have another vehicle push yours a little
uphill to take some of the pressure from the
parking pawl in the transmission. Then you
should be able to pull the shift lever out of
P (Park).

Shifting out of Park

The vehicle has an automatic transmission
shift lock control system. You have to fully
apply the brakes before you can shift from
P (Park) when the ignition is on. See
Automatic Transmission 0 135.
The shift lock control system is designed to
